Design Features in AutoCAD Mechanical

This section provides an overview of the functionality in the AutoCADMechanical software, including numerous innovative 2D design features.

Mechanical Structure

Mechanical structure comprises a suite of 2D structure tools for organizingdrawings and for reusing associative data. The capabilities of reuse in blocksand accessibility in layer groups are combined in mechanical structure. Whenyou start the AutoCAD Mechanical application, the Mechanical structureenvironment is enabled by default. You can also work with it disabled.

The mechanical structure tools include:

A browser interface for structured 2D mechanical design, where parts,assemblies, views, and folders containing associated data are organized,structured, and managed. Standard parts are automatically organized andmanaged in the browser. All components are accessible through the browserfor many functions, and filters can be set to control the type and level ofdetail of information displayed.

Folders in the browser are used for capturing elements of design for reuse.These elements provide all of the associative instancing benefits ofcomponents, but do not register as items in the live BOM database. Theycan contain geometry.

All geometry remains selectable and editable at all times using familiarcommands in open workflows. Workflows for structure can be bottom-up(recommended), middle-out (the most flexible and common workflow),and top-down (not the primary workflow).

Associative Design and Detailing

The browser is used to manage and reuse data in both the design and detailingdrafting stages. Many functions can be performed in the browser, includingthe following:

You can instance components and assemblies multiple times. The liveBOM database in AutoCAD Mechanical keeps track of the quantity of eachpart or assembly used.

Design Features in AutoCAD Mechanical | 7

Changes made to an associative instance of a part or assembly, associativecomponent, assembly detailing view, or a standard part or feature areautomatically reflected in the other instances.

Folders, components, and individual views of components can be reusedas needed. They maintain full associativity with each other.

Annotation views can be created for components and assemblies to fullydocument the design. Changes made to geometry result in associativedimensions being updated to reflect the change.

External References for Mechanical Structure

External References for mechanical structure provides for the components ofa drawing to be inserted as an external reference to multiple drawings.Conversely, multiple drawings can be attached as external references to asingle drawing.

The following are the key benefits of external references for mechanicalstructure:

Increased efficiency by allowing insertion of structure components frommany drawings as external reference associatively for concurrent design.

Reuse of parts from existing assembly drawings very quickly.

Those involved in multiple design projects that reference the same drawingare able to obtain the most updated design from the externally referencecomponent.

Ability to set up design specific reference directories as libraries for differentapplications.

Associative 2D Hide

The 2D hide situation tool in AutoCAD Mechanical automates the process toaccurately represent parts and features which are partially or completely hiddenin drawing views. The following are some of the 2D hide benefits:

Associative hide situations are managed in the browser.

The underlying geometry is not altered when you create an associativehide situation.


When geometry is hidden, AutoCAD Mechanical knows it is a componentin the mechanical structure, and provides a tooltip with the name andview of the component.

Autodesk Inventor Companion Support

Autodesk Inventor companion support redefines the meaning of 3D to 2Dinteroperability. Use the companion functionality to:

Access and associatively document native 3D part models without thepresence of Autodesk Inventor.

Visualize part models, examine and use part properties such as material,name, and number.

Associatively document part models using precision hidden-line removedprojections, dimensions, and annotations.

Link to the native Autodesk Inventor part models automatically notifiesyou of changes and enables updating of views and annotations to keepyour drawing up-to-date.

2D Design Productivity

These features increase productivity and reduce the number of steps neededto complete mechanical designs:

AutoCAD Mechanical provides an intelligent, customizable layermanagement system that puts objects on the appropriate layersautomatically.

Entities that are not on the current layer group, or entities that are on alocked layer group can be displayed in a different color to reduce screenclutter.

2D hidden-line calculations are based on defined foreground andbackground objects. You can choose hidden line representation types.

Auto detailing creates detailed drawings of individual components froman assembly drawing.

One set of power commands is used to create, update, and edit objects.

Autodesk Inventor Companion Support | 9

Mechanical line objects are available for creating centerlines and centercrosses, construction lines, symmetrical lines, section lines, break lines,and others.

Linear/symmetric stretch is used to modify dimensioned geometry bychanging the dimension value.

Predefined hatch patterns are applicable in two picks from toolbars andmenus.

Engineering Calculations

The automatic engineering calculations available in AutoCAD Mechanicalensure proper function in mechanical designs.

The 2D FEA feature determines the resistance capability of an object putunder a static load and analyzes design integrity under various loads.

A number of moment of inertia and beam deflection calculations areavailable.

Engineering calculations are available for shafts, bearings, and screws.

Machinery Systems Generators

Machinery systems in AutoCAD Mechanical generate the design andcalculation of shafts, springs, belts and chains, and cams. These tools ensurethat you get the design right the first time:

With the shaft generator, you can create drawing views of solid and hollowshafts. Common shaft features supported include center holes, chamfers,cones, fillets, grooves, profiles, threads, undercuts, and wrench fittings.Common standard parts supported include bearings, gears, retaining rings,and seals.

With the spring generator, you select, calculate, and insert compression,extension, and torsion springs, and Belleville spring washers in a design.You control the representation type of the spring, and create a spec formto incorporate in the drawing.

The belt and chain generator function provides features to create chainand sprocket systems, belt and pulley systems, calculate optimal lengths


for chains and belts, and insert these assemblies in your design. Chainsand belts can be selected from standard libraries.

The cam generator creates cam plates and cylindrical cams given inputborder conditions. You can calculate and display velocity, acceleration,and the cam curve path. You can couple driven elements to the cam andcreate NC data through the curve on the path.

Intelligent Production Drawing and Detailing

A number of commands are available in AutoCAD Mechanical that automatethe process to create balloons and bills of material.

You can create formatted balloons and bills of material, as well as detailedviews of portions of designs.

Multiple parts lists per drawing are supported. Grouping of a parts listprovides lists of like items. Selected items can be combined to calculatetotal length required for stock ordering. The parts lists recognize standardparts. You can format item numbers on parts lists.

Standard-sized drawing borders and customizable title blocks are available.

Intelligent and associative hole tables show a total count of each type ofhole along with a description of them. A second chart lists the coordinatesfor each of the holes selected. Any update to the holes is reflected in thecharts.

A language converter translates text on a drawing into one of seventeendifferent languages.

Revision control tables in drawings track revisions and display comments.

Fits lists chart all fits used in a drawing.

Detailing Productivity

Smart dimensions automatically maintain the proper arrangement witheach other.

Power dimension commands provide a single command to create and editall dimensions, apply specified formats, and add fits or tolerances.

Intelligent Production Drawing and Detailing | 11

Dimensions are automatic for 2D geometry with either ordinate or baselinedimensions.

One command quickly cleans up and arranges dimensions in 2D drawings.One system setting controls the scale for drawing symbols in all views.

Commands are available for align, break, insert, and join to easilydimension a drawing.

Annotations

Hole notes can be inserted for standard holes.

Commands are available to create standards-based surface texture symbols,geometric dimensioning and tolerances, targets, and weld symbols.

Fits description command creates fits descriptions for standard holes.

Leader command creates intelligent balloons and other leaders commonin mechanical drawings.

Standard Mechanical Content

Standard content includes parametrically generated, intelligent geometry thatyou can use to generate an object from scratch. The following are available:

About 600,000 standard parts, including screws, nuts, washers, pins, rivets,bushings, rings, seals, bearings, keys, and others, can be quicklyincorporated into any design.

About 8,000 standard features, including center holes, undercuts, keyways,and thread ends can be quickly incorporated into any design.

More than 20,000 standard holes, including through, blind, counterbored,countersunk, oblong, and others, can be quickly incorporated into anydesign.

Thousands of structural steel shapes, including U-shape, I-shape, T-shape,L-shape, Z-shape, rectangular tube, round tube, rectangular full beam,rectangular round beam, and others, can be quickly incorporated into anydesign.


Standard Parts Tools

Standard part tools provide for the elements that go with standard parts, suchas a hole to accompany a screw. These tools include:

Screw connection feature for selecting entire fastener assemblies at onetime.

Changeable representation of a standard part between a normal, simplified,or symbolic representation.

Power view to automatically generate a different view of a standard part,such as a top view from a front view.

Collaboration

Enjoy the benefits of design collaboration for your 2D output through AutodeskStreamline support. Autodesk Streamline is a hosted Web service for sharingpersonalized design data across the entire extended manufacturing enterprise.

Autodesk Streamline functionality includes the following:

Members can view and interact with the 3D data set published on AutodeskStreamline, without waiting for the data to download.

Using Streamline, many people can share design information andcollaborate online. Functionality includes instant messages, e-mailnotifications, polling/voting, discussion threads, database creation, andmore.

A layer made up of working layers and standard parts layers. Base layers are re-peated in every layer group.

base layer

A group of associated or related items in a drawing. A major advantage ofworking with layer groups is that you can deactivate a specific layer group and

a complete component. The drawing and its overview are enhanced with a re-duction in regeneration time.

A layer where the standard parts are put. All standard parts layers have the suffixAM_*N.

The layer where you are currently working.working layer


In AutoCAD Mechanical, you can use templates (*.dwt files) to create drawings.

Predefined templates, which contain settings for various drawings, such asam_iso.dwt or am_ansi.dwt, are supplied with AutoCAD Mechanical. You cancreate your own templates, or use any drawing as a template. When you usea drawing as a template, the settings in that drawing are used in the newdrawing.

Although you can save any drawing as a template, prepare templates to includesettings and drawing elements that are consistent with your company orproject standards, such as the following items:

unit type and precision

drawing limits

snap, grid, and ortho settings

layer organization

56 | Chapter 4 Working with Templates

title blocks, borders, and logos

dimension and text styles

linetypes and lineweights

If you start a drawing from scratch, AutoCAD Mechanical reads the systemdefaults from the registry. The system defaults have a predefined standard.

If you create a new drawing based on an existing template and make changesto the drawing, those changes do not affect the template.

To begin working with templates immediately, you can use the predefinedtemplate files stored in the acadm\template folder.

However, for this tutorial you create your own template.

If you are using Windows Vista and if UAC (User access Control) is enabled,in order to complete the exercices in this chapter, you must log on as a fulladministrator. Logging on as a user with administrator privileges is notsufficient, you must log on using the built in administrator account.

Setting Up Starting Layers

Each time you start AutoCAD Mechanical, layer 0 is active. Since layer 0 doesnot belong to the Mechanical layers, it is not displayed in the Layer Controldialog box of AutoCAD Mechanical if you select Mechanical Layer in the Showfield.

It is required that you specify the mechanical layer AM_0 as the default startinglayer.

To specify a starting layer

1 Start the Layer Control command.Toolbutton
